Our research aimed to study the correlation between the readings and the color space CIE Lab* values in two cultivars of sp. during leaf senescence and to evaluate the statistical criteria used in the selection of the best fit calibration functions. We demonstrate the importance of the Akaike information criterion and the parsimonious function besides the coefficient of determination. The reliability of the functions was tested by 's test comparison between the chlorophyll (Chl) estimated from SPAD readings and their chemical concentrations. Polynomial and Hoerl function described well the changes in Chl and total Chl (+) during senescence, but calibration functions are required to perform for each cultivar. We demonstrated that CIE Lab* system is reliable to estimate SPAD reading at stages of leaf senescence of sp. and can be used instead of .
我们的研究旨在探讨某物种两个栽培品种在叶片衰老过程中读数与颜色空间CIE Lab值之间的相关性，并评估用于选择最佳拟合校准函数的统计标准。除了决定系数外，我们还证明了赤池信息准则和简约函数的重要性。通过对从SPAD读数估算的叶绿素（Chl）与其化学浓度进行t检验比较，测试了这些函数的可靠性。多项式和霍尔函数很好地描述了衰老过程中Chl和总Chl（+）的变化，但每个栽培品种都需要执行校准函数。我们证明，CIE Lab系统在某物种叶片衰老阶段估算SPAD读数是可靠的，并且可以替代……使用。 （注：原文中部分内容表述不太完整准确，比如“sp.”“代替.”等，翻译时尽量忠实原文进行了处理）
